ABSTRACT

OBJECTIVE@#To describe the characteristics of the clinical presentation, diagnosis, surgical methods, and outcomes of patients with otogenic cerebrospinal fluid (CSF) leakage secondary to congenital inner ear dysplasia.@*METHODS@#A retrospective review was performed of 18 patients with otogenic CSF leakage secondary to inner ear dysplasia who underwent surgery in our group from 2007 to 2017 and had a follow-up of at least 4 months. The average length of follow-up was three years. The characteristics of the clinical presentations of all patients, such as self-reported symptoms, radiographic findings, surgical approaches and methods of repair, position of the leakage during surgery, and postoperative course, including the success rate of surgery, are presented.@*RESULTS@#The patients presented mostly with typical symptoms of meningitis, severe hearing impairment, and CSF otorrhea or rhinorrhea. All 18 patients had at least one previous episode of meningitis accompanied by a severe hearing impairment. The preoperative audiograms of 17 patients showed profound sensorineural hearing loss, and one patient had conductive hearing loss. Twelve patients presented with an initial onset of otorrhea, and two had accompanying rhinorrhea. Six patients complained of rhinorrhea, two of whom were misdiagnosed with CSF rhinorrhea and underwent transnasal endoscopy at another hospital. High-resolution computed tomography (HRCT) images can reveal developments in the inner ear, such as expansion of a vestibular cyst, unclear structure of the semicircular canal or cochlea, or signs of effusion in the middle ear or mastoid, which strongly suggest the possibility of CSF otorrhea. The children in the study suffered more severe dysplasia than adults. All 18 patients had CSF leakage identified during surgery. The most common defect sites were in the stapes footplates (55.6%), and 38.9% of patients had a leak around the oval window. One patient had a return of CSF otorrhea during the postoperative period, which did not re-occur following a second repair.@*CONCLUSIONS@#CSF otorrhea due to congenital inner ear dysplasia is more severe in children than in adults. The most common symptoms were meningitis, hearing impairment, and CSF otorrhea or rhinorrhea. HRCT has high diagnostic accuracy for this disease. The most common fistula site was around the oval window, including the stapes footplates and the annular ligament.

ABSTRACT

The measurement of heart rate variability (HRV) has the advantages of noninvasiveness and simple operation and is widely used in clinical trials and scientific research for assessing reactions of the autonomic nervous system. More and more studies on acupuncture also take HRV as an important index. In addition to the definition, origin, analytical methods, and significance of time domain and frequency domain parameters of HRV, we reviewed the situations of application of HRV to acupuncture research in recent years, analyzed the influence of acupuncture and sham acupuncture, different acupuncture methods, and different acupoints on HRV, and confirmed the role of HRV in reflecting the effect of acupuncture on the vagal and sympathetic systems. However, various interference factors for HRV measurement and diverse methods for data analysis may lead to great differences in the experimental results of HRV and the interpretation of parameters. Therefore, careful analysis is needed in future studies on acupuncture with HRV as an observation index.

ABSTRACT

It has been shown that ischemia preconditioning (IPC) can attenuate the myocardial injury induced by ischemic and reperfusion. But it was rarely used in clinic due to its inoperability. Previous studies indicate that electroacupuncture (EA) pretreatment can mimic myocardial ischemia preconditioning (MIPC) to produce cardioprotective effect. The activated adenosine A 2 b receptor has been proven to be involved in mediating the cardioprotection of IPC. In the studies on acupuncture analgesia, it was reported that adenosine receptor was activated by acupuncture stimulation, and acupuncture pretreatment can affect the acti-vities of intracellular A 2 b receptor. Based on those mentioned above, it is highly likely that the A 2 b receptor may also participate in the cardioprotection produced by acupuncture pretreatment. In this paper, we comprehensively reviewed relevant studies regarding 1) the cardioprotective effect of IPC and its limitations, 2) the similar cardioprotection produced by both acupuncture pre-treatment and IPC, 3) the mechanism underlying myocardial ischemic injury and intracellular calcium regulation, 4) the acti-vation of adenosine receptors and effects of acupuncture, 5) the relationship between adenosine receptors and intracellular calcium ion, and 6) the effect of acupuncture on adenosine receptors, so as to provide a novel assumption that A 2 b receptor may be a key factor in mediating the cardioprotection of acupuncture pretreatment. Our future research will systematically explore the me-chanism of acupuncture pretreatment in protecting ischemic myocardium from myocardial cell adenosine A 2 b receptor and intracellular calcium signal transduction related factors.

ABSTRACT

Eight sub-databases of pharmacological information on rational use of medicines were designed and established. These sub-databases cover dosing frequency, therapeutic drug priority to auxiliary medication, infusion shelf-life after admixture, incompatibility of two continuous infusion in the vein infusion tube, chronopharmacology, drug interaction involved in administration sequence , venous irritative drugs and preventive medicine. Once the standing order delivery to PIVAS involves any of these sub-databases, the system will prompt in turn " Auxiliary" , " Time limit" , " Taboo" , " Chronopharmacology" , " Interaction" , " Irritative" and " Preventive (therapeutic)" , starting from therapeutic drug priority to auxiliary medication. Pharmacists would make a reasonable sequence of the corresponding infusion and label the administration sequence on the infusion tag according to the prompt.Compared to the circumstance prior to this system, the wards with the infusion sequence labeling and equipped with intelligent prompt increased from 2 to 43; the percentage of such inpatients increased from 0.50% to 66.33%; the percentage of medical orders increased from 0.72% to 78.94%. The time spent by pharmacists for the same workload reduced from 73.44 h per day to 1.94 h per day. The times of flushing infusion tube reduced from 34.42 to 1.49 per ward and per day. The cost of flushing infusion tubes reduced by a big margin. PIVAS has established a method of regulating infusion administration sequence by an intelligent prompt system, based on improved safety and effectiveness of medication.

ABSTRACT

<p><b>OBJECTIVE</b>To observe the effect of acupuncture on the Notch signaling pathway in rats with traumatic brain injury and to explore the pathogenesis of acupuncture intervention on traumatic brain injury.</p><p><b>METHODS</b>Feeney's freefall epidural impact method was used to establish a traumatic brain injury model in rats; the rats were randomly divided into a normal group, sham operation group, model group and acupuncture group. Acupuncture was performed in the Baihui (DU 20), Shuigou (DU 26), Fengfu (DU 16), Yamen (DU 15) and Hegu (LI 4) acupoints in the rat, and Yamen was punctured via Fengfu. Then, the rats in each group were randomly divided into three subgroups, namely the day 3 subgroup, day 7 subgroup and day 14 subgroup according to treatment duration. The modified neurological severity scores (mNss) method was used to perform neurobehavioral scoring for evaluating the degree of injury in the rats. The hematoxylin-eosin (HE) staining method was used to observe the pathological change in the brain tissue of rats in each group. Real-time fluorescent quantitative polymerase chain reaction (Q-PCR) technology was used to detect changes in the Notch1, Hes1 and Hes5 gene expression levels in the cortex on the injured side. Western blot was used to detect the protein expression changes.</p><p><b>RESULTS</b>One day after modeling, the mNss scores in the model group and in the acupuncture group were significantly higher than those in the normal and sham operation groups (P<0.01) ; there was no statistically significant difference between the normal group and the sham operation group. The scores decreased with increased treatment time, and the scores in the acupuncture group decreased more significantly than those in the model group (P<0.01). The pathological examination by the HE staining method demonstrated that the brain tissue of the rats in the acupuncture and model groups relatively significantly changed. The Notch1 gene expression level in the acupuncture group was significantly higher than the level in all of the other groups (P<0.01) ; the Hes1 and Hes5 gene expression levels were also higher in the acupuncture group. The expression changes of the Notch1 and Hes1 protein were consistent with that of mRNA. In each experimental group, the mNss score and the pathological results by the HE staining method were consistent with the mRNA results.</p><p><b>CONCLUSION</b>Acupuncture could significantly promote high expression levels of Notch1, Hes1 and Hes5 in the brain tissue of traumatic brain injury rats. Therefore, acupuncture might be an important intervention for inducing endogenous stem cell proliferation and for promoting nerve repair.</p>
